Thank you to the gentleman who sent me the necessary pinout info
for the 80287. I connected pin 39 (clock multiplier) to 5V and that did
it, actually over did it. The 287 is now running at 12MHz, a little over
the 10Mhz the chip is rated for and above the CPU's 10Mhz.
Is running the 287 above its rated speed harmful or dangerous? I know
that the chip will probably heat up more, but will it affect anything else
in the computer? I do have a heat sink that I can put on the chip to help
cool it, but I don't how to attach the heat sink. Is there a readily
available heat-conductive glue that I can use for this job?
Replies to the above questions will be appreciated.
